Lisp is easier to use through the Emacs editor.
Gnu Emacs can be
dowloaded free, for either Linux or Windows.
If you wish to use Gnu Common Lisp (GCL), you can copy the files
/projects/cs394p/.emacs and /projects/cs394p/.lisp.el
to your directory;
these facilitate use of Lisp within emacs. You will also need to have
/p/bin in your path, since xgcl is /p/bin/xgcl.
This can be done by adding the following line to your .login file:

setenv PATH {$PATH}:/p/bin

Alternatively, you could put in a local link to xgcl with the following
commands to unix:

To use Lisp within emacs, first start emacs . Then give the
command C-x 3 (control-x 3) to split the window vertically into
two halves (or C-x 2 (control-x 2) to split horizontally).
With the cursor in one half-window, give the command
M-x run lisp (meta-x run lisp) to start Lisp. You now can
run Lisp within one window and edit your Lisp code in the other half.
Putting your cursor at the start of a function definition in one
window and giving the command C-M-z (control-meta-z)
will send the definition to Lisp. You can also save your Lisp source
code to a file and load the file from Lisp, e.g. (load "myfile.lsp") .

Increasing Stack Space

In Gnu Common Lisp (GCL), if the variable *multiply-stacks*
is set to a positive fixnum,
then the next time through the TOP-LEVEL loop, the loop will be exited.
The size of the stacks will be multiplied by the value of
*multiply-stacks*, and the TOP-LEVEL will be called again.
Thus to double the size of the stacks:

(setq si::*multiply-stacks* 2)

It is necessary to exit TOP-LEVEL, because it and other lisp functions
maintain pointers into the stacks, which would be incorrect
when the stacks have been moved. Interrupting the process of
growing the stacks could leave Lisp in an inconsistent state.
